The final total mission cost was $224 million which consisted of $124.9 million for spacecraft development, $44.6 million for launch support and tracking, and $54.6 million for mission operations and data analysis.

NEAR-Shoemaker uzay aracı 17 Şubat 1996'da Cap Canaveralen'den Eros'a bir Delta-2 roketiyle başlatıldı. NEAR-Shoemaker did not prove or disprove this link to the satisfaction of scientists. Near Earth Asteroid Rendezvous Shoemaker (NEAR Shoemaker), first spacecraft to orbit and then land on an asteroid (Eros, a near-Earth asteroid, on Feb. 12, 2001). Eros çevresinde yörüngesel yerleştirme , 14 Şubat 2000 tarihinde UT 15: 33'te (10:33 EST), NEAR, Eros'un yörüngesine çok yakın olan 13 aylık bir güneş merkezli yörüngeyi tamamladıktan sonra gerçekleşti. Kontrolcüleri şaşırtacak şekilde, uzay aracı hasar görmemiş ve inişten sonra saniyede 1,5 ila 1,8 metre (böylece bir asteroide yumuşak iniş yapan ilk uzay aracı haline gelmiş) tahmini bir hızla çalışır durumda idi. The Near Earth Asteroid Rendezvous – Shoemaker (NEAR Shoemaker), renamed after its 1996 launch in honor of planetary scientist Eugene Shoemaker, was a robotic space probe designed by the Johns Hopkins University Applied Physics Laboratory for NASA to study the near-Earth … The total mass of the instruments was 56 kg, and they required 80 W power. Kamera ile Eros görüntüleri çekildi, veriler IR'ye yakın spektrograf ile toplandı ve uçuş sırasında radyo takibi yapıldı. Bu bağlantı kurulduktan sonra, göktaşı malzemesi büyük, karmaşık ve gelişen ekipmanlarla incelenebilir ve sonuçlar uzaydaki cisimlere ekstrapole edilebilir. The craft was three-axis stabilized and used a single bipropellant (hydrazine / nitrogen tetroxide) 450 newton (N) main thruster, and four 21 N and seven 3.5 N hydrazine thrusters for propulsion, for a total delta-V potential of 1450 m/s.

Images of Eros from the first flyby - 23 December 1998, Information on the NEAR Mathilde Flyby NEAR-Shoemaker was the first spacecraft to orbit and (though this was not originally planned) to land on an asteroid – Eros. The scans were for scientific purposes and to mitigate any chances of collision with a satellite.

A new plan was put into effect in which NEAR flew by Eros on December 23, 1998 at 18:41:23 UT at a speed of 965 m/s and a distance of 3827 km from the center of mass of Eros. 1200 km of the C-class asteroid 253 Mathilde on 27 June 1997. The spacecraft's thrusters fired thousands of times during the anomaly, which expended 29 kg of propellant reducing the program's propellant margin to zero. Between December 1999 and February 2001 NEAR Shoemaker used its gamma ray spectrometer to detect gamma ray bursts as part of the InterPlanetary Network.[2]. The mission succeeded in closing in with the asteroid and orbited it several times, finally terminating by touching down on the asteroid on 12 February 2001.
