Weather looks good for NASA’s Perseverance rover launch to Mars

Watch Live! NASA's Mars Perseverance Launch

The weather looks promising for NASA to launch its Perseverance rover to Mars on Thursday, July 30.

NASA has set Thursday for its planned launch of the rover, which will travel alongside a small helicopter called Ingenuity which will be the first heavier-than-air craft to fly on another planet. The pair will be launched atop an Atlas V rocket from Cape Canaveral in Florida.

However, such launches are always dependent on the weather. Weather reports from Tuesday this week looked good for the launch to go ahead, and in the early hours of Thursday, the reports continued to be positive.

In the latest weather briefing, @45thspacewing meteorologists continue to forecast an 80% chance of favorable conditions for liftoff from Cape Canaveral this morning. Weather is good for proceeding into fueling operations.

Meteorologists from the 45th Space Wing of the United States Space Force confirmed there was an 80% chance of favorable conditions for the launch. “Weather is good for proceeding into fueling operations,” United Launch Alliance (ULA), the launch provider for the Atlas V rocket, announced on Twitter.

A weather report by the 45th Space Wing regarding the launch area released on July 29 described “overall conditions are favorable,” but did warn that, “an isolated shower just offshore and mid-level clouds along the coast are likely as a surface trough off the coast of the southeast U.S. sags southward.”

The main concerns regarding weather that could disrupt the launch are the presence of thick clouds, which are estimated to have a 20% chance of impacting the launch.

If the launch does need to be delayed, there are two backup windows. The first is on the morning of Friday, July 31, when there are risks for isolated showers, and the second is on the morning of Saturday, August 1, when there is a slight chance of anvil clouds.

The rover’s mission

The launch will carry the Perseverance rover to Mars, aiming to land on the Red Planet in February 2021. The rover will land in the Jezero crater, an ancient dried-up lake bed, where it will search for evidence that there was once microbial life on the planet.

The rover is around 10 feet long and weighs 2,260 pounds, which makes it around the size and weight of a small car. It has a seven-foot-long robotic arm and is armed with a range of cameras, microphones, and instruments such as spectrometers for analyzing rock samples.

NASA scientists hope that, using these instruments, they can conduct a search for ancient life on the planet.

If you want to tune into the launch live, we have all the details of how to watch.

Perseverance rover catches footage of a dust devil on Mars
mars 2020 perseverance rover

Many of the weather events we experience here on Earth can be found on other planets too, and that includes whirlwinds. Several missions have observed small whirlwinds called dust devils on Mars, and the Perseverance rover recently captured footage of one such dust devil in action as it rolled across the martian surface.

The footage was captured by one of Perseverance's black-and-white navigation cameras, called Navcams, and shows a dust devil moving at a speed of around 12 mph across a regions known as the Thorofare Ridge. You can clearly see the dust devil as a white column moving across the top of the ridge in an animation posted by NASA's Jet Propulsion Laboratory, which manages the rover.

NASA’s Mars rover, Perseverance, has used its self-driving smarts to successfully navigate its most challenging route since arriving on the planet two-and-a-half years ago. Even better, its advanced technology meant it took just a third of the time that it would’ve taken other NASA Mars rovers.

Perseverance rover’s Mars oxygen machine comes to the end of its mission
Technicians at NASA's Jet Propulsion Laboratory lower the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) instrument into the belly of the Perseverance rover.

The experiment to make oxygen on Mars has come to an end, with the Perseverance rover's MOXIE instrument completing its mission. MOXIE, or Mars Oxygen In-Situ Resource Utilization Experiment, is a small box tucked inside the rover that takes in carbon dioxide from the Martian atmosphere and converts it into oxygen. After 16 successful runs, the experiment has now been concluded.
