Today is a milestone in NASA’s Perseverance mission to Mars. At 1:40 pm Pacific time today, the rover will have traveled 235.4 million km (146.3 million miles). That means the spacecraft is halfway to Mars and its rendezvous with Jezero Crater. The spacecraft isn’t traveling in a straight line, and the planets are moving, so it’s not equidistant to both planets.
“Although we’re halfway into the distance we need to travel to Mars, the rover is not halfway between the two worlds,” Kangas explained. “In straight-line distance, Earth is 26.6 million miles [42.7 million kilometers] behind Perseverance and Mars is 17.9 million miles [28.8 million kilometers] in front.”
But today’s still a good time to take another look at Jezero Crater, and why NASA chose it as the mission’s target.

Today’s the day! The OSIRIS-REx spacecraft is going to reach out and boop asteroid Bennu! You can watch the broadcast here as the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission attempts to collect a sample of an asteroid on Tuesday, Oct. 20, at 6:12 pm EDT (5:12 pm CDT, 3:12 PDT).

It’s been a long road for InSight’s Mole. InSight landed on Mars almost two years ago, in November 2018. While the lander’s other instruments are working fine and returning scientific data, the Mole has been struggling to hammer its way into the surface of the planet.
After much hard work and a lot of patience, the Mole has finally succeeded in burying itself all the way into the Marian regolith.
But the drama hasn’t concluded yet.

The CNSA (Chinese National Space Agency) has released an image of its Tianwen-1 spacecraft to coincide with the National Day and Mid-Autumn Festival. The spacecraft is on its way to Mars, and if the landing is successful, China will be only the third nation to successfully land a spacecraft on the planet.

In this decade and the next, some very impressive missions will take place. For instance, NASA will send its robotic Europa Clipper orbiter investigate Jupiter’s icy moon Europa for the first time. The orbiter will launch sometime in the middle of the decade (likely 2024) and arrive in the Jovian sytem in the 2030s to look for possible signs of life.
In preparation for this momentous event, NASA recently released a stunning new mission poster. As you can see, the poster features the orbiter looking down on Europa’s icy surface with Jupiter hanging in the background. The orbiter itself is in shadow so as to draw attention to the landscape beneath it.

In an expected move, the Japan Aerospace Exploration Agency (JAXA) has announced a mission extension for their Hayabusa2 spacecraft. Hayabusa2 will be sent to rendezvous with another asteroid in a few years time.
It’s target is 1998 KY26, a near-Earth object (NEO) less than a kilometer in diameter. But it’ll take a while and some maneuvering around other objects in the Solar System to reach its goal. JAXA says the spacecraft will arrive at the asteroid in July 2031.

Gravity is good for a lot of things. It brings objects closer together. Occasionally they crash into each other. But sometimes two objects get locked in a unique gravitational dance that pairs them together. That dance can be short-lived, or it can last for billions of years. In some cases the objects are large (i.e. planets and moons), but they can also be quite small.
These small dancing objects are called binary asteroids, and we know very little about them, despite making up approximately 15% of all asteroids in the solar system. That is until a newly greenlighted NASA mission, called Janus, will arrive at two different binary asteroids around 2026.

People have been speculating about the possibility of life on Mars for centuries. But it’s only since the 1970s and the Viking 1 and 2 missions that we have been able to search for it. After many decades, evidence has mounted that Mars may have once supported life (like the existence of flowing water and organic molecules), but evidence of present-day life has remained elusive.
Unfortunately, according to a recent study by an international team of scientists led by the Spanish Astrobiology Center (CSIC-INTA), it’s possible that the surface of Mars was bathed in acid and alkaline fluids that destroyed all evidence of past life. These findings could have serious implications for upcoming missions to Mars, which includes NASA’s Perseverance and the ESA’s Rosalind Franklin rover.

The discovery of phosphine in the upper clouds in Venus’ atmosphere has generated a lot of excitement. On Earth, phosphine is produced biologically, so it’s a sign of life. If it’s not produced by life, it takes an enormous amount of energy to be created abiologically.
On other planets like Jupiter, there’s enough energy to produce phosphine, so finding it there isn’t surprising. But on a small rocky world like Venus, where there’s no powerful source of energy, its existence is surprising.
This discovery clearly needs some more investigating.

In August 2014, the ESA’s Rosetta spacecraft arrived at its destination, Comet 67P/Churyumov-Gerasimenko, after a 10 year journey. Rosetta carried a small companion, the Philae Lander. On November 12th, Philae was sent to the surface of Comet 67P. Unfortunately, things didn’t go exactly as planned, and the lander’s mission lasted only 63 hours.
During that time, it gathered what data it could. But mission scientists weren’t certain of its precise location, meaning its data was difficult to interpret accurately. Only when scientists knew precisely where Philae was located on the comet, could they make best use of all of its data.
