	4660 Nereus (Site not responding. Last check: 2007-09-07)
		It is an Apollo asteroid, with an orbit thatfrequently comes very close to Earth, and because of this it isexceptionally accessible to spacecraft.
		Nereus was scheduled for visitation by both the private Near EarthAsteroid Propector probe, and the Japanese Hayabusa probe.
		However, the formerproject is defunct, and Hayabusa 's delay in launching caused it to be redirected to 25143 Itokawa.

		Measurements of the 1- and 2-micron absorption bands within the spectrum of Otawara reveal it to be an S(IV)-type asteroid (Fornasier et al submitted 2002), with an interpreted mineralogy that is consistent with it being a reddened ordinary chondrite.
		The neutral to slightly red spectral slope of Nereus places it in the X-complex.
		The visible wavelength spectrum clearly reveals an absorption feature at 0.49 microns, placing Nereus definitively within the Xe class, suggesting an association with the enstatite achondrite meteorites.

		JPL Universe - Jan 19, 1998 - A formal project office was established in 1997 to manage the U.S. contribution to the Japanese-managed Muses-C mission to collect and return to Earth a sample from an asteroid.
		This innovative mission will use new flight technology, including solar electric propulsion, to send a spacecraft to asteroid 4660 Nereus and deliver a JPL-developed rover, which measures about the size of a shoebox, to the asteroid's surface.
		The Japanese Muses-C spacecraft will also fire explosive charges into the asteroid, collect the samples that are ejected from the impacts, and return the samples to Earth in a capsule for laboratory analysis.

		The mission, which is purely profit-driven, was urged on Benson by the scientific community, including astronomers at the cutting-edge Jet Propulsion Laboratory in Pasadena, Calif., a division of the California Institute of Technology that defines and conducts most deep-space missions for NASA.
		Nereus, which is a half-mile across and travels in a solar orbit between Earth and Mars, will be extremely close to us in January 2002.
		Benson finds NEAR to be "a good mission to try to emulate." NEAR won't land on the asteroid, but will orbit around Eros for a year once the two cross paths a second time, in February 2000.

		Abstract: An Apollo asteroid (4660) Nereus is one of the most accessible asteroids by spacecraft.
		Photometric observations of light variation of Nereus were performed in order to support a mission scenario planning and to elucidate the origin of the asteroid.
		The results revealed that Nereus has a long rotational period, 15.1 ± 1.2 hours, and that the amplitude of light variation is fairly large.

	Capitalism in space: Corporate claim on an asteroid
		In a world where the capitalist market dominates social life, and the right to buy and own private property is considered natural and God-given, the drive to acquire more and more wealth can take on bizarre forms.
		Jim Benson, one of the founders of the corporation Space Dev, recently announced his intention of spending $79 million to have the US space agency NASA build and launch a space probe to rendezvous with an asteroid known as 4660 Nereus in the year 2002.
		Clearly the mission to 4660 Nereus is aimed at staking more than just a claim to a space boulder.

		Instead of the vision of Stanley Kubrick and Arthur C. Clarke -- Pan Am flights to an orbiting space station -- the real 2001 will see the launch of NEAP, the potential harbinger of a new age that may be stranger than fiction.
		The NEAP mission will observe Nereus over a period of one to three months, during which the spacecraft will drop scientific instruments on the surface.

		As for Nereus, its orbital evolution is typically dominated by Earth encounters, causing a random walk in semimajor axis.
		According to our results, it is unlikely that this (C-type) NEA comes from a comet-like initial orbit, or at least that such a transition has occurred in the last $\approx 10$ Myr.
		Eros probably reached its present orbit by a ``slow-track'' evolution dominated by Mars encounters, and is a comparatively old fragment originated by a large-scale collision occurred in the main belt.

		Although they are interesting design concepts, many researchers are skeptical and have argued that their payload capabilities, ranges, and lifetimes are likely to be limited and that such rovers, thus, are of less scientific value in the near term than their larger brethren.
		Practical experience with the operation of such a vehicle will come with the deployment of a 1-kg microrover on asteroid 4660 Nereus in 2003.
		This vehicle (Figure 3.2), one of NASA's contributions to Japan's MUSES-C asteroid sample-return mission, is intended to carry a camera, an infrared spectrometer, and an alpha x-ray spectrometer derived from Sojourner's APXS.

	SpaceDev Signs JPL For Mission Support
		The NEAP spacecraft is planned to launch in 2001 and by mid-2002 should brendezvous with the asteroid 4660 Nereus for a two-month primary mission.
		Starting immediately, engineers in JPL's Telecommunications and Mission Operations Directorate (TMOD) will initiate the process for allocating its world-wide DSN resources to support tracking, commanding and telemetry reception for NEAP in 2002, principally during the spacecraft's cruise to Nereus and during operations in close proximity to the approximately 1-kilometer-(0.6-mile-) diameter body.
		"To meet our NEAP launch readiness date of early 2001 and Nereus rendezvous date of mid-2002, we have to get the DSN tracking pass-allocation process started now," said Rex Ridenoure, SpaceDev's Chief Mission Architect.
