NASAs newest Mars mission, the Perseverance rover, is now halfway to the red planet, the space agency announced on Tuesday, October 27, 2020. Its the latest milestone for the mission that will be the first since the Viking 1 and 2 landers in the 1970s/1980s to look directly for evidence of microbial life on Mars.
Julie Kangas, a navigator for the mission, said in a statement:
At 1:40 p.m. Pacific Time today, our spacecraft will have just as many miles in its metaphorical rearview mirror as it will out its metaphorical windshield. While I dont think there will be cake, especially since most of us are working from home, its still a pretty neat milestone. Next stop, Jezero Crater.
The Perseverance rover reached its halfway point to Jezero Crater on Mars on Oct. 27, 2020 at 1:40 p.m. PDT (4:40 EDT). There are now 146.3 million miles (235.4 million km) left to travel. Image via NASA/ JPL-Caltech.
Since its launch on July 30, 2020, Perseverance has travelled 146.3 million miles (235.4 million km). That means that as of last Tuesday, the spacecraft is halfway to Mars (kind of). Kangas explained:
Although were halfway into the distance we need to travel to Mars, the rover is not halfway between the two worlds. In straight-line distance, Earth is 26.6 million miles [42.7 million km] behind Perseverance and Mars is 17.9 million miles [28.8 million km] in front.
Perseverances flight path is a curved trajectory due to the gravitational influence of the sun, which also affects the relative motion of the two planets.
By the time the rover reaches Mars on February 18, 2021 it will have covered 292.5 million miles (470.8 million km). At that point, it will take 11.5 minutes for radio signals to get from Earth to Mars, and vice-versa.
The spacecraft also continues to be in good health. The mission team tested the RIMFAX and MOXIE instruments onboard on October 15, and found them to be in good shape. RIMFAX will probe the ground beneath the rover with radar and MOXIE will attempt to produce oxygen from the Martian atmosphere, aprocedure that could be used by future astronauts for oxygen to breathe and to burn rocket fuel for the return trip back to Earth. On October 16, theX-ray tube in the PIXL instrument was tested, as well as the MEDA instrument on October 19, with similar results. PIXL will analyze the fine scale elemental composition of rocks and soil, while MEDA will study temperature, wind speed and direction, pressure, relative humidity and dust size and shape.
Jezero Crater, the landing site for Perseverance, used to be a lake a few billion years ago, making it a prime location in the search for past microbial life. Image via NASA/ JPL-Caltech.
According to Keith Comeaux, deputy chief engineer:
If it is part of our spacecraft and electricity runs through it, we want to confirm it is still working properly following launch. Between these checkouts along with charging the rovers and Mars Helicopters batteries, uploading files and sequences for surface operations, and planning for and executing trajectory correction maneuvers our plate is full right up to landing.
Perseverance will land in Jezero Crater, which, a few billion years ago, held a lake. There is even an ancient delta where a river once emptied into the lake, and the rover will touch down near it.
Because the crater is an ancient lakebed with clays and sediments, the landing site is considered to be a prime location to search for traces of ancient microbial life. While the Viking landers looked for current life, Perseverance will focus on past life. It is still, however, the first Mars mission since then to have astrobiology as its primary mission. Other rovers, like Spirit and Opportunity (MER) and Curiosity, are more geology-focused, looking for evidence of past habitable conditions rather than life itself.

As well as analyzing rock and soil samples in its onboard laboratory, Perseverance will store some of the samples for later return to Earth by another mission. This is the first time such a sample return from Mars will be attempted.
The rover, about the size of a car, is very similar in design to the Curiosity rover, but with updated instruments including ones specifically for searching for trace chemical or fossil evidence of past microbial life.
Perseverance also has a companion on this mission, a small drone-like helicopter called Ingenuity. It will fly ahead of the rover, acting as a scout to view the terrain from above and help spot interesting features for the rover to drive to. If successful, it will be the first-ever aircraft to be flown in the atmosphere of another planet.
The key objectives of the Perseverance mission include:
Explore a geologically diverse landing site Assess ancient habitability Seek signs of ancient life, particularly in special rocks known to preserve signs of life over time Gather rock and soil samples that could be returned to Earth by a future NASA mission Demonstrate technology for future robotic and human exploration

With the halfway mark now attained, there are only about four more months until Perseverance lands on Mars. This will be an exciting mission, one that not only will provide more clues as to what Mars used to be like billions of years ago as a more habitable world but perhaps even discover the first solid evidence for ancient life hidden in the dust-covered rocks and sand.

Bottom line: NASAs Perseverance rover mission has passed the halfway mark in its journey to Mars.
