NASA is gearing up to launch its next Mars rover. Dubbed 2020, the roving scientist is set to blast off to the Red Planet next year, aiming to find signs of life and bag samples for eventual return to Earth.

The rover, scheduled to launch next summer, will touch down in February 2021. It’s landing site: a 28-mile-wide crater on the Martian surface, dubbed Jezero Crater, which scientists think hosted a lake in Mars’s past.

Recent data collected from the Mars Reconnaissance Orbiter also shows that Jezero contains mineral deposits known to preserve microfossils here on Earth.

Hydrated silica is one such mineral and thanks to the eagle-eyed orbiter, scientists have identified not one but two patches in the crater.

Orbital imagery has also revealed the remnants of a large delta in Jezero. Deltas are the place where rivers drain into a lake. These are promising areas for life and one of the main factors in choosing this specific location as the landing site.

“The landing site in Jezero Crater offers geologically rich terrain, with landforms reaching as far back as 3.6 billion years old, that could potentially answer important questions in planetary evolution and astrobiology,” Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate said in a news release.”Getting samples from this unique area will revolutionize how we think about Mars and its ability to harbor life.”

But that’s not the only exciting discovery at Jezero. Carbonate minerals were also found. This is exciting because many organisms here on Earth use carbonate minerals to make sturdy structures, like seashells. These structures can last for billions of years once fossilized.

Scientists say that carbonates plus evidence of ancient water is the perfect combination for preservation. Meaning it’s an excellent spot to search for any signs of past lifeforms and to uncover clues about Mars’s climate history.

Carbonates are not biosignatures or signs of life, but they’re an exciting discovery because they form from the interaction between water and carbon dioxide. So they could also tell us how Mars transitioned from a warm and wet climate to the harsh, cold desert world we see today.

“The possibility that the ‘marginal carbonates’ formed in the lake environment was one of the most exciting features that led us to our Jezero landing site. Carbonate chemistry on an ancient lakeshore is a fantastic recipe for preserving records of ancient life and climate,” Ken Williford Mars 2020 Deputy Project Scientist said in a statement. “We’re eager to get to the surface and discover how these carbonates formed.”

The Mars 2020 rover will scan the crater in search of any potential biosignatures. To that end, the robotic scientist will act as a remote geologist, studying rocks in fine details, caching samples for later return to Earth, and using special instruments to identify minerals in rocks.

Another big aspect of the Mars 2020 mission will be to collect samples for eventual return to Earth, where scientists around the world can study the material.

Mars 2020, will receive an official name before launch as part of a student naming competition hosted by NASA. The six-wheeled rover is destined to touch down in Jezero crater on Feb. 18, 2021, following a July 2020 launch. Around the same time, it’s European counterpart, the Rosalind Franklin ExoMars rover will arrive on Mars at a soon-to-be-announced location.

SpaceX is rolling out a new feature to Starlink that could be a lifesaver in some instances, but more of a luxury for others.

Starlink is the satellite internet service that Elon Musk’s company SpaceX launched several years ago. It has been adopted by many people at their homes, many airlines on their planes, and many maritime companies on their ships.

It has been a great way for customers to relieve themselves of the contracts and hidden fees of traditional internet service providers.

Now, Starlink is rolling out a new service feature on its units called “Standby Mode,” which is part of Pause Mode. The company notified customers of the change in an email:

“We’re reaching out to you to let you know the Pause feature on your plan has been updated. Pause now includes Standby Mode, which comes with unlimited low-speed data for $5.00 per month, perfect for backup connectivity and emergency use. These updates will take effect in 30 days. All of your other plan features remain the same. You are able to cancel your service at any time for no charge.”

SpaceX did not define how fast these “low speeds” will be. However, there are people who have tested the Standby Mode, and they reported speeds of about 500 kilobytes per second.

The mode is ideal for people who might deal with internet or power outages, but still need to have some sort of internet access.

It could also be used as a backup for people who want to stay with their ISP, but would like to have some sort of alternative in case of an outage for any reason.

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Musk says SpaceX is aiming for a timeline of roughly three weeks from now, which would come about ten weeks after the previous launch.

Coincidentally, it would bring the two launches 69 days apart, and if you know anything about Elon Musk, that would be an ideal timeline between two launches.

SpaceX is coming off a test flight in which it lost both the Super Heavy Booster and the Upper Stage in the previous launch. The Super Heavy Booster was lost six minutes and sixteen seconds into the flight, while SpaceX lost communication with the Ship at 46 minutes and 48 seconds.

Musk is aiming for the tenth test flight to take place in early August, he revealed on X:

This will be SpaceX’s fourth test flight of the Starship program in 2025, with each of the previous three flights bringing varying results.

IFT-7 in January brought SpaceX its second successful catch of the Super Heavy Booster in the chopstick arms of the launch tower. The ship was lost after exploding during its ascent over the Turks and Caicos Islands.

IFT-8 was on March 6, and SpaceX caught the booster once again, but the Upper Stage was once again lost.

The most recent flight, IFT-9, took place on May 27 and featured the first reused Super Heavy Booster. However, both the Booster and Upper Stage were lost.

The Federal Aviation Administration (FAA) hit SpaceX with a mishap investigation for Flight 9 on May 30.

SpaceX is preparing for a new launch date for the Ax-4 mission to the International Space Station (ISS).

SpaceX, Axiom Space, and NASA addressed recent technical challenges and announced a new launch date of no earlier than Thursday, June 19, for the Ax-4 mission. The delay from June 12 allowed teams to assess repairs to small leaks in the ISS’s Zvezda service module.

NASA and Roscosmos have been monitoring leaks in the Zvezda module’s aft (back) segment for years. However, stable pressure could also result from air flowing across the hatch seal from the central station. As NASA and its partners adapt launch schedules to ensure station safety, adjustments are routine.

“Following the most recent repair, pressure in the transfer tunnel has been stable,” a source noted, suggesting the leaks may be sealed.

“By changing pressure in the transfer tunnel and monitoring over time, teams are evaluating the condition of the transfer tunnel and the hatch seal between the space station and the back of Zvezda,” the source added.

SpaceX has also resolved a liquid oxygen leak found during post-static fire inspections of the Falcon 9 rocket, completing a wet dress rehearsal to confirm readiness. The Ax-4 mission is Axiom Space’s fourth private astronaut trip to the ISS. It will launch from NASA’s Kennedy Space Center in Florida on a Falcon 9 rocket with a new Crew Dragon capsule.

“This is the first flight for this Dragon capsule, and it’s carrying an international crew—a perfect debut. We’ve upgraded storage, propulsion components, and the seat lash design for improved reliability and reuse,” said William Gerstenmaier, SpaceX’s vice president of build and flight reliability.

The Ax-4 mission crew is led by Peggy Whitson, Axiom Space’s director of human spaceflight and former NASA astronaut. The Ax-4 crew includes ISRO astronaut Shubhanshu Shukla as pilot, alongside mission specialists Sławosz Uznański-Wiśniewski from Poland and Tibor Kapu from Hungary. The international team underscores Axiom’s commitment to global collaboration.

The Ax-4 mission will advance scientific research during its ISS stay, supporting Axiom’s goal of building a commercial space station. As teams finalize preparations, the mission’s updated launch date and technical resolutions position it to strengthen private space exploration’s role in advancing space-based innovation.
