MIT researchers detail plans for private missions to search for life on Venus

A suite of new privately-funded missions will be heading to Venus to search our neighboring planet for signs of life. In a recently released report, researchers from MIT have detailed more about their plans for the Venus Life Finder (VLF) missions.

Although Venus is in many ways highly inhospitable, with its high surface temperatures and crushingly thick atmosphere, people have long speculated that there could be microbial life in its clouds. The potential finding of the biomarker phosphine there last year drew considerable public interest, although subsequent research shows that the phosphine finding was likely incorrect. Even so, the VLF researchers argue in the report that, “Venus is a compelling planet to search for signs of life because of the habitable temperatures in the cloud layers and because of many atmospheric chemical anomalies that together are suggestive of unknown chemistry and possibly the presence of life.”

In order to learn more about Venus, the VLF proposes a suite of missions which will be privately funded. The idea is to send a series of low-cost missions with specific scientific goals, to complement bigger missions like NASA’s DAVINCI+ and VERITAS and the European Space Agency’s ENVISION.

“We hope this is the start of a new paradigm where you go cheaply, more often, and in a more focused way,” said Sara Seager, principal investigator for the planned Venus Life Finder Missions, in a statement. She was also a member of the team that made the disputed phosphine detection. “This is a newer, nimbler, faster way to do space science.”

The VLF mission will begin with a probe from Rocket Lab to be launched in 2023. The probe will skim for three minutes through the Venusian atmosphere, aiming to collect data about the chemistry there.

“There are these lingering mysteries on Venus that we can’t really solve unless we go back there directly,” said Seager. “Lingering chemical anomalies that leave room for the possibility of life.”

“People have been talking about missions to Venus for a long time,” she went on to say. “But we’ve come up with a new suite of focused, miniaturized instruments to get the particular job done.”

How we could search for life on Saturn’s icy moon Enceladus
best cassini images 7

When it comes to searching for places beyond Earth where life could thrive in our solar system, some of the most intriguing targets aren't planets but rather moons. From Jupiter's icy moons like Europa to Saturn's moon Enceladus, these places are thought to host liquid water oceans beneath thick ice crusts which could potentially support life. Now, new evidence suggests support for the habitability of Enceladus, and NASA is developing missions to travels to these distant moons and search for evidence of life.

The research about Enceladus, published in the journal PNAS, shows that there seems to be dissolved phosphorus in the moon's ocean, which is an important ingredient for life. It is used in the creation of RNA and DNA, is found in cell membranes, and is found within our bodies in out bones and teeth. By studying data from the Cassini probe, the researchers were able to create a model of the ocean of Enceladus and how minerals would dissolve in it.

SpaceX eyes mission to extend life of NASA’s Hubble Space Telescope
The Hubble Space Telescope floats above Earth.

SpaceX is working with NASA to explore the possibility of using its Dragon spacecraft to push the Hubble Space Telescope to a higher orbit, thereby extending the life of the mission.

Hubble has been operating for the last 32 years in an orbit around 335 miles above Earth, capturing stunning imagery and gathering data to help scientists learn more about the universe and its origins. But its orbit is slowly decaying, leaving NASA with the choice of finding a way to raise Hubble to a more stable orbit in a move that would extend the mission by years, or eventually losing it as it falls back to Earth.

NASA inks deal for 2nd private astronaut mission to space station
The space station and Earth.

Five months after wrapping up its first private mission to the International Space Station (ISS), NASA has confirmed a second one for spring next year.

As with its first private ISS mission, the space agency will work with Texas-based Axiom Space for the second voyage, and also use SpaceX flight equipment to transport the crew.
