Researchers will thoroughly examine this rocky treasure in the forthcoming years. Scientists aim to decipher clues about the origins of our planet, the intricacies of our solar system, and potentially, the emergence of life on Earth.
How to watch the OSIRIS-REx landing
For space enthusiasts wanting to witness this historic event, the capsule is scheduled to penetrate Earth’s atmosphere on September 24, 2023, at a blistering speed of around 27,650 mph. For those eager to catch the action live, NASA will be broadcasting the landing starting 10 a.m. EDT on NASA TV, the NASA app, and on their official website.
Rich Burns, the project manager for OSIRIS-REx at NASA’s Goddard Space Flight Center, likened this mission to a marathon. He remarked, “We are now in the final leg of this seven-year journey, and it feels very much like the last few miles of a marathon, with a confluence of emotions like pride and joy coexisting with a determined focus to complete the race well.”
Once secured, they will transport the capsule to a temporary clean room on the military range. Here, it will undergo a series of initial processing steps and disassembly, preparing it for its subsequent journey to NASA’s Johnson Space Center in Houston. In Houston, researchers will document, preserve, and eventually disseminate the valuable sample to scientists worldwide for in-depth analysis.
Potential risks involved
Returning an asteroid sample to Earth with the OSIRIS-REx mission carries immense scientific potential. However, it has also raised some concerns among certain segments of the population. Here are the primary reasons for these apprehensions.
Potential biohazards of an asteroid sample
One of the chief concerns revolves around the possibility, however unlikely, that the asteroid sample could contain extraterrestrial microorganisms or substances harmful to life on Earth.
If such organisms exist and were to be inadvertently introduced to our environment, the consequences are unpredictable. This concern mirrors the worries some had when the Apollo astronauts returned from the Moon. Ultimately, this led to them being quarantined upon their return.
Sample containment
Closely related to the biohazard concern is the worry about the integrity of the sample return capsule. If the capsule were to rupture upon re-entry or landing, it could potentially release the asteroid material into the Earth’s environment.
Impact risk
Though the sample capsule is relatively small and designed for a controlled re-entry, there’s always a minute risk with any object re-entering the Earth’s atmosphere. Accidents, however improbable, can occur.
Precedent for future missions
Some concerns arise from a broader perspective on space exploration. If we begin regularly retrieving samples from various celestial bodies, each return poses its own set of risks. Setting a precedent with OSIRIS-REx might accelerate our pursuit of similar missions without sufficient public understanding or debate.
