Mars: beautiful, desolate, and the planet in the solar system whose seasons most closely match ours.

The European Space Agency (ESA) recently released an image of the red planet’s north polar region and its stunning ice caps. The image coincided with the Seventh International Conference on Mars Polar Science and Exploration which took place last week (Jan. 13 to 17) in Argentina.

The image, taken by the Mars Express orbiter, highlights some of the natural processes that shape the planet’s surface.

Mars may seem like a dry, desert-like world devoid of water, but its supply is locked up at the poles. Thick layers of water ice cover the Martian polar regions all-year long, with an added layer of frozen carbon dioxide forming in the frigid winter months.

In the image, the Martian terrain peeks through the ice, appearing as zebra stripes. This view highlights the stark contrast between the ice and ruddy Martian terrain.

The stripes are part of larger spiral patterns that emanate outward from the center of the north pole. But what causes them?

Scientists think that this unique pattern is formed by katabatic winds, that carry higher-density air to lower elevations. On Mars, these winds ferry cold, dense air from the regions’ glaciers down to lower elevations containing valleys and depressions.

At the same time, Mars is rotating (just like the Earth) creating another cool phenomenon called the coriolis effect, which manifests as the spiral pattern we see in the image. (On Earth, the Coriolis force is seen in weather events such as hurricanes.)

Scientists are very interested in the ice deposits covering Mars’s polar regions. Not only do they contain evidence that can tell us how the red planet’s climate has changed over millions of years, but it’s also a source of water for future human missions.

The Mars Express orbiter was designed to study the red planet’s surface processes over time, documenting seasonal changes at the poles as well as track winds and any storms that pop up.

To date the orbiter has lived up to the task, expanding our understanding of just how wet ancient Mars was. It also sheds light on activities below the planet’s surface.

Understanding what sort of processes are happening at the poles will help inform future human missions to the red planet, especially in regards to the search for water.

Water is a precious commodity and if there are other places thanks to some recent data, NASA is hoping that future missions can land a bit further south, near a region called Arcadia Planitia, and rely on its water resources instead of having to travel to the poles and hauling water back.

Elon Musk updates the SpaceX timeline for Mars

Elon Musk has updated his timeline for when humans will walk on Mars and for when ships will simply get there.

The objective of getting to Mars has been one of Musk’s biggest goals since becoming a serial entrepreneur and realizing that time on Earth is limited. Musk has said several times he hopes to die on Mars, and not by impact.

Musk now believes that people will be on Mars in “roughly 5 to 7 years.” He said that a Mars lander will get there “a few years sooner.”

The response from Musk comes after NASA Administrator Jared Isaacman said that SpaceX’s biggest priority is the Moon and not Mars. Because of this, Isaacman conceded that he believes nuclear power and propulsion investments will provide “potentially the pathway with the fewest miracles required to put four people on Mars in the next 10 to 15 years.”

Of course, this is what NASA can do through taxpayer funding and nuclear investments, he added.

Musk’s grand ambitions are much more optimistic than most, and it is certainly a double-edged sword. This is not the first time timelines for Mars have been somewhat lofty, especially to those normal thinkers like you and me, not super geniuses like Musk.

SpaceX Board has set a Mars bonus for Elon Musk

In fact, the SpaceX and Tesla frontman has said on at least a dozen occasions that we could be on Mars in the coming years. Musk said 2020 would be the big year as early as 2009. In 2020, he was “highly confident” of a landing in 2026, and had even said 2024 in a best-case scenario.

The point is, the range has varied, and it’s anyone’s guess when we’ll get there. This latest adjustment to the timeline is typical of Musk, and while the Moon has seemingly taken priority over Mars, it is still worth mentioning that the ultimate goal is to make life multiplanetary, and it starts potentially with the Red Planet.

SpaceX gets an absolutely crazy price target after rough IPO

Published

SpaceX (NASDAQ: SPCX) got an absolutely crazy price target rating from Raymond James after the company experienced a tough first few weeks following its Initial Public Offering (IPO).

Despite the tumultuous start, SpaceX has plenty of believers, and the company’s massively successful Starship launch last Friday, its 13th test flight of the massive rocket, went so smoothly that Raymond James analysts pushed its price target on the company to roughly 7 times its current trading level.

SpaceX Starship just nailed something it’s never done before

The firm officially put a “Strong Buy” rating and an $800 price target on the stock. It currently trades at around $113. Its all-time high is $225.64, reaching this trading level shortly after shares first went public.

Raymond James’ price target is tied to the firm’s confidence after Starship’s 13th test flight. Analysts at the firm said it was an incremental step that reduces engineering risks, citing the widely successful heat shield test that CEO Elon Musk recently detailed, the smooth deployment of Starlink V3 satellites, and a successful in-space engine relight.

SpaceX also managed to see Starship splash down safely in the Indian Ocean, while the Super Heavy Booster fell down to the Gulf of America with no incidents.

It is interesting to see these launches have such a tremendous impact on the stock and what investors think of it. After SpaceX initially delayed the Starship launch last week, shares fell tremendously. Most probably did not realize that the stand-down is a standard practice, especially if everything is not perfect.

The mission was initially aborted due to an issue with Raptor engines. This was resolved, and Starship launched last Friday after another delay on Thursday, which was caused by weather.

Now that analysts have seen what SpaceX launches are capable of and how impressive the feat is, firms are adjusting their price targets accordingly, making it known that they have high expectations for the space exploration company.

Elon Musk responds to Volvo’s latest LiDAR decision

Published

Tesla CEO Elon Musk has responded to reports that Volvo is officially discontinuing the LiDAR sensor on two of its cars.

Volvo announced that it would officially scrap LiDAR systems on its EX90 and ES90 vehicles in various markets. In Norway, owners will get a €1,800 compensation for features that will never arrive due to this decision. There will be no option to remove the unit from vehicles, either.

The issue stems from Volvo’s supplier, Luminar, and its bankruptcy filing. Luminar will no longer be able to supply LiDAR units to Volvo for the EX90 and ES90, effectively axing any use the unit has on vehicles. Volvo will phase out the data collection processes via the LiDAR system, and it will not be utilized whatsoever.

Musk saw the story on X and responded, stating:

“I did try to warn them. Humans drive using neural nets and optical sensors. Same is true for robot cars.”

Musk has been publicly vocal about his disdain for LiDAR systems, once calling them “a fool’s errand,” as he has consistently kept the outlook that they are not needed for effective self-driving.

The typical example used as evidence for this by Musk is humans themselves: made with only eyes and memories, humans are capable of navigating a car by using what they can see and what they’ve personally experienced on the road.

Elon Musk argues lidar and radar make self driving cars more dangerous

“Same is true for robot cars,” Musk says, as Teslas have eight exterior cameras that help see everything surrounding the vehicle, and a neural network that analyzes behavior and tendencies with every mile driven.

Tesla is a vision-only self-driving company that ditched sensors and radar several years ago in favor of cameras. Behind this effort, the company has established a reputation for having one of the most robust self-driving platforms in the world.

Musk’s big bet with Tesla on its self-driving program’s strategy has widely paid off. Other companies continue to utilize things like LiDAR, radar, and sensors for effective self-driving, but Tesla has shown that there is more than one way to give consumers a strong and accurate driver assistance suite.

The real question is: who will be the first company to take Musk’s advice and attempt a self-driving platform based on cameras only, or even license FSD for themselves?
