In about five years ’ time , a potentially hazardous asteroid will drop by Earth at an eerily close distance of less than 20,000 miles ( 32,000 klick ) . During this rarefied encounter , Apophis will be ten multiplication closer to Earth than the Moon and scientists want to take full advantage of its visit .
Apophis is a on trajectory towards an Earth flyby on April 13 , 2029 . When it was first discover in 2004 , the 1,100 - foot - wide ( 335 beat ) near - Earth object was designate as a wild asteroid that could impact our satellite . Later observations , however , reassured scientists that there ’s no pauperization to panic just yet , and that the asteroid hasno opportunity of crashing into Earth for at least another hundred .
That ’s very good news show cave in the sizing of this object and the serious damage it would visit should it some day strike our satellite . Hopefully that ’ll never materialize , but object of this size tend to attain Earth about once every 80,000 years , unleashing ruinous damage and world-wide - scale impact winters .

During its coming flyby , scientists need to explore the asteroid to determine whether Earth ’s gravitative field will have an impact on Apophis ’ orientation , composing , and spin . It could leave in asteroid temblor , for example , causing a switching in how its material are distributed within , or change the visual aspect of its Earth’s surface . Scientists go for to chronicle these possible changes by comparing observations of the asteroid before and after its 2029 encounter with Earth . forcible changes to the asteroid could change its orbital way of life , so it ’s intelligibly something scientist will want to document .
Private blank companies like Blue Origin and startup Exploration Labs , or ExLabs , have arrive up with proposal for missions to rendezvous with Apophis before its anticipated flyby , SpaceNewsreported . During a late shop at a European Space Agency centerfield in The Netherlands , the companies pitched their missionary work conception in an effort to pick up more about the asteroid and other space rock that could pose a potential risk to Earth .
Blue Origin ’s proposal admit using itsBlue Ring orbital platformto deliver payload to Apophis . Blue Ring , which is position to make its unveiling by the end of 2024 , is design to supply end - to - end service for both commercial and authorities customers , and can host freight that weigh up to 6,600 pounds ( 3,000 kilograms ) .

The orbital platform can be used to deliver instrument or deployable ballistic capsule to Apophis for scurvy - monetary value , low - risk missions , Steve Squyres , chief scientist at Blue Origin , is quoted in SpaceNews as say .
For its proposal , ExLabs submit an idea that had previously been hit the books by NASA ’s Jet Propulsion Laboratory ( JPL ) . deal Radar Observations of Interior Distributions , or DROID , would post a spacecraft to Apophis that deploys two cubesats to do a “ CAT scan ” of the asteroid ’s national , according to SpaceNews . The mission would launch in May 2028 and arrive at Apophis in February 2029 .
to begin with in February , NASA host a workshopto seek ideas from the individual sector “ on forward-looking approaches to bear delegation during the Earth flyby of the asteroid Apophis in 2029 . ”

NASA ’s OSIRIS - APEX spacecraft , formerly get it on as OSIRIS - male monarch , is alreadyon its way to study Apophisand observe vary the asteroid may bear from its close coming upon with Earth . After drop offsamples from the Bennu asteroidin the Utah desert , the ballistic capsule was repurposed for a new errand , having to carry out close passes to the Sun , as well as three Earth solemnity assists , to pass Apophis in five twelvemonth .
The space means also has a plain brace of spacecraft that can be repurposed to study the Apophis asteroid . The Janus military mission was suppose to set up in August 2022 , hitching a ride to blank with the Psyche spacecraft to explore a metallic element - rich asteroid . An unfortunate software program glitch delayed Psyche ’s launch two month before its liftoff , therebyaffecting its drive - along missions .
Psyche later launched in October 2023 , but its new launch windowpane could not deliver Janus ’ twinned probes to the delegation ’s original target . As a resolution , the space vehicle were taken off the launch manifest and stowed away at Lockheed Martin .
The duet of spacecraft were originally mean to jaw asteroids 1996 FG3 and 1991 VH , but could be repurposed to study Apophis rather . Although there are some difference between Apophis and the original targets of the Janus mission , the twin probe can still expect out a flyby and run exchangeable observations of Earth ’s incoming visitor .
And this is just the scratch line . Other missions could be herald in the coming months and years given the scientific importance and rarity of such a tight skirmish .
