Time is Ticking: Scientists Push for Action on Apophis Mission

In a race against time, scientists are appealing to NASA to accelerate efforts on mission concepts aimed at the near-Earth asteroid Apophis. This crucial action is expected before the asteroid's alarmingly close approach to our planet scheduled for April 2029.

Reviving the Janus Smallsats

Recently, a set of recommendations emerged from the Apophis T-4 Years Workshop, held in Tokyo last month. The scientists proposed that NASA should utilize two twin Janus smallsats, originally meant for asteroid flybys, to explore Apophis. These satellites have been in limbo since NASA scrapped their original mission due to delays in the Psyche mission.

A Unique Opportunity for Exploration

The Janus spacecraft, storing vast potential, could provide valuable insights into Apophis just before it zips by Earth. This additional research is expected to complement NASA’s planned observations post-flyby, making it a pivotal moment in planetary defense.

NASA's Current Stance and Future Plans

Currently, there’s been little discussion from NASA regarding the Janus or any new plans for an Apophis mission since the call for information proposals last October. During a recent congressional hearing, Nicky Fox, the associate administrator for science at NASA, implied that alternative approaches for the expedition weren't feasible without significant funding, which is currently lacking.

What Comes After the Close Encounter?

Looking ahead, NASA does have an exciting mission planned. The OSIRIS-REx spacecraft, now rebranded as OSIRIS-APEX, is set to reach Apophis shortly after its near pass with Earth, gathering crucial low-resolution images to study the asteroid’s surface alterations due to tidal forces.

International Collaborations and Future Missions

Innovative collaborations are forming around Apophis as well. The European Space Agency is spearheading the RAMSES mission, targeting a visit to Apophis before its flyby. Financial backing will be sought at their upcoming ministerial conference. Additionally, the Japanese space agency JAXA is developing a mission called DESTINY+, which could potentially pass near Apophis while en route to Phaethon, the parent body of the Geminid meteor shower.

A Collective Urgency for Action

The consensus from the workshop is clear: missions like OSIRIS-APEX, RAMSES, and DESTINY+ are top priorities for understanding Apophis and must be fully funded to meet their scientific goals. The urgency is emphasized, as timely funding and decision-making are critical to ensuring these missions come to fruition before 2029.

The World is Watching

As the clock ticks down to the flyby, the global community keenly anticipates the outcomes of these ambitious missions. The workshop's ultimate plea resonates: swift action is essential not only for scientific advancements but for the safety and understanding of humankind’s cosmic neighborhood.
