NASA’s OSIRIS-APEX safe After Searing Pass of Sun

Engineers of NASA's osiris-Apex spacecraft given details about Osiris spacecraft after passed sun in close point in its path about its now situation and ists future plans and more

Engineers of NASA’s OSIRIS-APEX (Origins, Spectral Interpretation, Resource Identification – Apophis Explorer) spacecraft were confident about its closest ever pass of the Sun on Jan. 2, 2024.


Their models had predicted that, despite traveling 25 million miles closer to the heat of the Sun than it was originally designed to, OSIRIS-APEX and its components would remain safe.


The mission team confirmed that the spacecraft indeed had come out of the experience unscathed after downloading stored telemetry data in mid-March. The team also tested OSIRIS-APEX’s instruments in early April, once the spacecraft was far enough from the Sun to return to normal operations. Between December 2023 and March, OSIRIS-APEX was inactive, with only limited telemetry data available to the team on Earth.


Engineers of OSIRIS-APEX placed it in a fixed orientation with respect to the Sun and repositioned one of its two solar arrays to shade the spacecraft’s most sensitive components during the pass.



Now spacecraft is in elliptical orbit around sun. For every nine months it will get closer to sun.To get on a path that will allow it for future missions (apophis 2029)


In January space craft went to near point of sun in its assigned path as engineering expected safely crossed that point.beside of it engineers found surprises while testing spacecraft components. A couple of instruments came out better than expected after exposure to higher temperatures


Since April 13 2023 in recent test engineers observed 70% reduction in hot pixes in cameras, which are commonly used in space,hots pixes shown up white spots in image it is because of exposure or detective to high radiation of sun


OSIRIS-APEX needs to execute five more exceptionally close passes of the Sun — along with three Earth gravity assists — to get to its destination.



The second OSIRIS-APEX perihelion is scheduled for Sept. 1, 2024. The spacecraft will be 46.5 million miles away from the Sun, which is roughly half the distance between Earth and the Sun, and well inside the orbit of Venus.

 Nasa secussesfully launched the Sentinel-6 Michael Freilich Satellite to the space in 2020  NASA secussesfully launched the Sentinel-6 Michael Freilich Satellite to space in yesterday.you know friends this space craft full details for that iam tell this space craft full details in this.because hear so many times same matter you have bore.so for that iam tell full details of that space craft. The nasa launched the Sentinel-6 Michael Freilich Satellite to the space in planned time.the planed time is :12:17 pm in November 21.so by the fixed time the nasa launched this rocket. Friends this is last rocket in this month.and rocket launching have in December month.  Friends rocket launching only finished but nasa make some events before after month.so the nasa make any events like space walk and teleconference.etc......... any events  So friends you want to know nasa makes events lasted updates.so you must & should subscribe my blog.if you subscribe my blog.If iam make or give any

 Nasa today launching the Sentinel-6 Michael Freilich Satellite to the space in 2020 Friends nasa today launching the Sentinel-6 Michael Freilich Satellite to space.this satillite is launching for observe the levels of ocean tides and all things about the ocean. Because in this time in america have come so many big winds and also rains.and tsunamis.and in the beach near regions are phasing problems.for that the nasa make this satillite and launching into space.you have come one dought.the nasa launch so many satillites.that satillites are avaible in the space in this also. So that satillite make give this work. Yes your dought is correct.but that are satillites are not made for this work.and that satillites are have not observe the ocean.but the Sentinel-6 Michael Freilich Satellite observe the ocean in 24 hours.for that the nasa launching this satillite. This satillite work is only observe the ocean and give the result to nasa team.fot that this satillites nasa maked fastly.and

 Nasa conducted the 4th time of orion capsule Dropdown test for Artemis in 2021. Friends nasa was conducted the 4th time of capsule Dropdown test for Artemis mission.with crew or without crew. This tests are conducted in series.so in that series this is the 4th test.that test video ianm given below.so once see that video. In this tests conducted without crew inside capsule. This test was conducted on may 20 2021.nasa not only conducted capsule test only conducting also SLS boosters test also. Nasa new administration also ask funds for nasa new projects like Artemis missions.and james webb telescope like projects. Friends if you like this post please share with your friends. Thankyou...................
