===Orbits and landing=== [[File:Erosregolith.jpg|thumb|right|200px|Eros from approximately 250 meters altitude (area in image is roughly 12 meters across). This image was taken during ''NEAR''{{'s}} descent to the surface of the asteroid.<ref>{{cite web |title=Final Images from 2001 Feb 12 |url=http://near.jhuapl.edu/iod/20010214/index.html |website=near.jhuapl.edu |access-date=17 April 2022}}</ref>]] Following the flyby, ''NEAR'' moved to a 200 km circular orbit and shifted the orbit from [[direct motion|prograde]] near-polar to a retrograde near-equatorial orbit. By December 13, 2000, the orbit was shifted back to a circular 35 km low orbit. Starting on January 24, 2001, the spacecraft began a series of close passes (5 to 6 km) to the surface and, on January 28, passed 2 to 3 km from the asteroid. The spacecraft then made a slow controlled descent to the surface of Eros, ending with a touchdown just to the south of the saddle-shaped feature Himeros on February 12, 2001, at approximately 20:01 UT (3:01 p.m. EST). To the surprise of the controllers, the spacecraft was undamaged and operational after the landing at an estimated speed of 1.5 to 1.8 meters per second (thus becoming the first spacecraft to soft-land on an asteroid).<ref>{{cite book|url=https://www.nasa.gov/sites/default/files/atoms/files/beyond-earth-tagged.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://www.nasa.gov/sites/default/files/atoms/files/beyond-earth-tagged.pdf |archive-date=2022-10-09 |url-status=live|title=Beyond Earth: A Chronicle of Deep Space Exploration, 1958–2016|page=2|last1=Siddiqi|first1=Asif A.|lccn=2017059404|isbn=9781626830424|publisher=NASA History Program Office|edition=second|year=2018|id=SP2018-4041|series=The NASA history series|location=Washington, DC}}</ref> After receiving an extension of antenna time on the [[Deep Space Network]], the spacecraft's gamma-ray spectrometer was reprogrammed to collect data on Eros's composition from a vantage point about {{convert|4|in}} from the surface where it was ten times more sensitive than when it was used in orbit.<ref name=phone>{{Cite news | title = The End of an Asteroidal Adventure: NEAR Shoemaker Phones Home for the Last Time | last = Worth | first = Helen | date = February 28, 2001 | publisher = [[Applied Physics Lab]] | url = http://near.jhuapl.edu/news/flash/01feb28.html}}</ref> This increase in sensitivity was in part due to the increased ratio of the signal from Eros compared to the noise generated by the probe itself.<ref name=Trombka /> The impact of cosmic rays on the sensor was also reduced by about 50%.<ref name=Trombka>{{cite journal |author=Trombka, J.
