NASA Mars rover promises blazing entrance after China, UAE make it to Mars orbit
The month of the robotic invasion of Mars is upon us. Seven months ago, the United States, China, and the United Arab Emirates launched missions on a 300 million mile (480 million kilometer) journey to Mars.
Last week, two of the three missions quietly arrived and inserted themselves into Mars orbit. The final spacecraft to arrive, NASA’s Mars 2020 Perseverance mission, however, will not go gently into the Martian atmosphere. On Thursday, February 18, NASA’s latest Mars mission destined to uncover evidence of ancient microbial life on the distant planet is set to touchdown following a spectacular display of extremely complex engineering.
Getting to Mars
Launching to the Red Planet is a strategic maneuver that can only be completed once every two years. This is due to the varying speeds and the elliptical shape of the planets’ orbits around the sun. The point at which Earth and Mars are aligned close enough to minimize travel time, called an opposition, occurs only once every two years.

The most recent opposition occurred in July 2020. Four international Mars missions were intended to leave Earth that summer, however, due to required further certification of parachutes the European Space Agency’s ExoMars Rosalind Franklin rover would have to wait for its launch opportunity during the next planetary opposition to occur in 2022. That left three robotic invaders from the United States, the United Arab Emirates, and China to escape Earth’s orbit and become interplanetary superstars.
Hope arrives to Mars
The United Arab Emirates Space Agency’s first-ever interplanetary mission, a spacecraft named Al-Amal, or the Hope Probe, was developed in collaboration between the Mohammed bin Rashid Space Center, Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder, Arizona State University, and the Space Sciences Lab at the University of California, Berkeley. It was launched on July 19, 2020, from Tanegashima Space Centre in Japan aboard an H2A202 rocket. On Tuesday, February 9, the Hope Probe was the first of the three missions to complete the journey to Mars and successfully insert itself into orbit.
The Hope Probe arrived to near-Mars orbit traveling approximately 75,000 mph (121,000 kph), far too fast to successfully achieve a safe Martian orbital insertion maneuver. In order to slow down to the approximate 11,000mph (18,000 kph) needed to be captured by Mars orbit, the spacecraft had to autonomously fire its main thrusters and perform a Mars Orbit Insertion burn lasting an agonizing 27 minutes. To compensate in the instance of a thruster failure, there was a backup safety protocol that would’ve doubled the length of the burn. After 27 grueling minutes, the Mohammad Bin Rashid Space Center located in Dubai reported that the maneuver was completed successfully and the Hope Probe had arrived at its final destination.

Unlike the American and Chinese missions to Mars which will land rovers on the surface, the United Arab Emirates’ Hope Probe will remain in Mars orbit for the duration of its mission – approximately two Martian years. The spacecraft is equipped with a suite of three instruments, two spectrometers – one infrared and one ultraviolet – to study the Martian atmosphere, and one imager to capture high-resolution images to study the surface from afar.
China’s Tianwen-1 Rover will hang out in orbit before landing in May
The same type of Mars Orbit Insertion maneuver was completed by China’s first interplanetary mission, the Tianwen-1 spacecraft. Launched from China on July 23, 2020, Tianwen-1 arrived at Mars orbit just one day after the Hope Probe on Wednesday, February 10.
The Tianwen-1 spacecraft had to autonomously complete an excruciating 11-minute “braking” burn to slow down which took it behind the planet as it was captured by Mars gravity and entered into orbit.
Like NASA’s Perseverance, the Tianwen-1 mission features a rover that will eventually land on the surface of Mars. The process to get the rover to the surface, however, varies from that of NASA’s Mars 2020 Perseverance mission.
The Tianwen-1 spacecraft is made of two components, an orbiter and a rover. Currently, it is planned that the orbiter will spend some time in Mars orbit for a period of comprehensive observation before attempting a landing of the rover in May. Ideally, the spacecraft will then touch down in a region known as Utopia Planitia.

Once the rover safely makes it to the surface it will initiate the investigation period of the mission. The rover carries a suite of scientific instruments that will be used to investigate the composition of the Martian surface searching for the potential distribution of water and ice. Similar to China’s Yutu 2 rover which is exploring the Moon, the Tianwen-1 rover also carries a panoramic camera to image the planet.
Perseverance and Ingenuity like no other
The last of the three Mars missions – NASA’s Mars 2020 Perseverance mission launched on July 30, 2020, from Cape Canaveral Space Force Station aboard a United Launch Alliance Atlas 5 rocket. As far as Mars arrivals go, the best has certainly been saved for last. Following the success of the other two missions from China and the United Arab Emirates, the stage is set for Perseverance to make its dramatic entrance.

NASA’s Mars 2020 Perseverance mission is by far the most ambitious mission to launch to Mars during the 2020 planetary transfer window. NASA is not attempting to land one, but two spacecraft on the surface of Mars. The $2.4 billion Mars 2020 mission is comprised of the Perseverance rover – powered by the heat produced by radioactive decay of Plutonium – and a first of its kind rotary helicopter called Ingenuity. It is scheduled to arrive in dramatic fashion on Thursday, February 18.
Rather than conducting a braking maneuver to slow down and enter Mars orbit, the Perseverance spacecraft will autonomously conduct the entry, descent, and landing (EDL) procedure – essentially going from traveling several thousand miles an hour to descending slowly under a parachute canopy to softly land in mere minutes.
The spacecraft – housed in a protective aeroshell with its robust heat shield facing the planet’s surface – will burst into Mars’ atmosphere traveling nearly 12,500 mph (20,000 kph). Once through, Pesevereance will ditch its heat shield and autonomously begin scanning the Martain terrain to determine its relative location and make adjustments to find an optimal landing spot. Then, a powered descent module will deploy transporting the rover the rest of the way down slowing to less than 2mph (3kph). Finally, the descent module will hover and deploy a complex harness system lowering Perseverance – and its stowaway, the Ingenuity helicopter – to the Martian surface for touchdown.

After seven months of interplanetary travel, it all comes down to the final seven minutes – the length of time the EDL process is expected to take. All spacecraft controllers back on Earth can do is watch and wait for that final telemetry reading indicating that Perseverance has successfully touched down. That is why this process has earned the nickname “seven minutes of terror.”
Beginning around 11:15 am PST (19:15 UTC) on Thursday, February 18th, NASA will provide live coverage of Perseverance’s landing attempt. The agency will carry the coverage on NASA TV and its website, as well as a number of other platforms including YouTube, Twitter, Facebook, LinkedIn, Twitch, Daily Motion, Theta.TV, and NASA App.

Tesla Roadster owners to get “Flying Stunt Mode” and looping track access
Musk says Roadster owners can command the unveiling stunts autonomously, with a Texas looping track.
Elon Musk says owners of the new Tesla Roadster will be able to ask the car to perform the stunts Tesla showed at its unveiling, with the car doing the driving itself. Musk made the comment Saturday in a reply on X to tech blogger Robert Scoble, and he added a promise of a looping track at Tesla’s Texas headquarters.
Scoble had argued that the person in the Roadster is not really driving it. In his description, the driver operates a computer that tells another computer what to do, with steering, braking and acceleration all handled by wire. Musk answered, “True. You will be able to ask the Roadster to perform any of the tricks shown autonomously, as it will be sentient. Also, we will have a wild looping track (crazier even than Hot Wheels) at our Texas HQ where you can test out your Roadster.”
@Scobleizer True.

At the October 15 event outside Waco, the car drove up a curved ramp until it was upside down, flew off on cold gas thrusters, flipped and landed. It also hovered over a Cybercab, Cybertruck, Semi, Model Y and Model 3 while moving. As we noted in our breakdown of the three Roadster configurations, Musk said at the event that the car “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. Saturday’s reply adds that the car would run them on its own.
Tesla has described some of the hardware that would make that possible. The Roadster uses steer by wire with a yoke, and its cold gas thrusters rely on electric actuators for small adjustments in flight. A fan system under the car creates suction, which Tesla says is strong enough to hold it upside down, a setup we covered in our look at the Roadster’s fan system and thrusters.
Musk did not say when an autonomous stunt feature might arrive, how it would work, or what he means by sentient. He also gave no size, location or opening date for the Texas track. Production is planned for Giga Texas in 2027 or 2028, and Tesla says the car is not approved for public road use. The Rocket version, the one built to fly, is invite only.
The comment follows a week of Musk teasing the event, including his claim that the demo would be a banger, which we covered before the stream. Tesla reports third quarter earnings on October 21, and shareholders can submit and vote on questions through the Say portal until 4 p.m. EDT on October 20, according to our earnings Q&A preview. A question about autonomous Roadster stunts and the Texas track would be a quick way to get specifics from management.

How to use Grok Bot to block spam calls and texts
Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.
Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.
The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.
Ask your @Grok @Bot to remove your phone number from spam call & text lists!

Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.
For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.
The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.
Investor's Corner
Tesla’s flying Roadster just revealed something bigger than the car
Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.
The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.
Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.
The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.
The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.
Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.
The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.
