The final flight of the Commercial Titan III occurred on 25 September 1992, and placed NASA's Mars Observer spacecraft into heliocentric orbit, by means of a Transfer Orbit Stage.

In the Tantrasangraha ( 1500 ), he further revised his planetary system, which was mathematically more accurate at predicting the heliocentric orbits of the interior planets than both the Tychonic and Copernican models.
33.
The LISA concept has a constellation of three spacecraft, arranged in an equilateral triangle with million-kilometre arms ( 2.5 million km ) flying along an Earth-like heliocentric orbit.
34.
It was originally intended to be so launched, but after the Centaur LH2 / LOX upper stage that would have been required to push it into a heliocentric orbit was banned from Shuttle use.
35.
These panels are in heliocentric orbit, including those from Apollos 13 17 whose S-IVBs impacted the moon, as the S-IVBs jettisoned them before maneuvering themselves into lunar impact trajectories.
36.
It should not be used for flights which are undergoing routine operations, such as spacecraft that have reached their operational orbits, or probes in heliocentric orbit coasting to their rendezvous with a planetary body.
37.
The Helios I and Helios II space probes, also known as Helios-A and Helios-B, were a pair of probes launched into heliocentric orbit for the purpose of studying c ).
38.
Orbital insertion around Eros occurred on 14 February 2000 at 15 : 33 UT ( 10 : 33 AM EST ) after NEAR completed a 13-month heliocentric orbit which closely matched the orbit of Eros.
39.
One of the ullage motors failed to fire, and when the main engine ignited for a four-minute burn to place the spacecraft into heliocentric orbit, the stage began to tumble out of control.
40.
This spacecraft was intended as a lunar probe, but failed to go past the Moon and into a heliocentric orbit as planned, but did reach an altitude of 102, 360 km before falling back to the Earth.
