Figure 1. The concept of single in-orbit debris surface capture involves a small probe (dashed line, diameter is about half a meter) sent into orbit by a mass driver, snagging a passing debris object and capturing it to orbit around a nearby celestial body. Deployment of a mass driver in orbit requires spacelaunch propulsion, and can be accomplished using conventional chemical propellants in a conventional booster or with a semi-reusable power source.

Today’s global economy depends on an infrastructure that includes trucking, container ports, ocean, air and rail transportation, utility power generation and distribution, and telecommunications networks. As our worldwide demand for goods and services has grown, there has been an uptick in the cost, time and risk associated with delivering products and services in a safe, reliable and cost-effective manner. In the absence of large-scale or long-term government-funded space programs to advance these industries, what can be done in-orbit to make shipments and deliveries more cost-effective, safe, reliable and efficient?
This challenge has become increasingly more relevant over the last decade as the cost of sending a variety of space assets to orbit has become increasingly small relative to the value of these assets. Therefore, the concept of single in-orbit debris surface capture is now being proposed to overcome this challenge, namely, an orbiter or other space asset is launched in orbit, and instead of using the full thrust of the launch vehicle to enter orbit, a small maneuverable mission is provided to temporarily capture a nearby passing debris object into orbit and subsequently direct the captured debris object to an orbit of interest.
This could be used to move payloads or other space objects from a small to a larger orbit, allowing a mass driver in orbit to be employed to do additional work on the payload (such as changing its orbit). In the context of the moon, debris in lunar orbit can be captured and directed to an orbit about the moon, where it could serve as a ‘dummy payload’ to avoid a critical period in lunar operations. In the context of the Earth, such a concept would reduce the number of launches and launches of redundant vehicles and payloads that might require a higher launch volume than could be accomplished with one-off
. By bassamitvi.Egmont (painting)
Egmont (also Egmont-Bund, Catalan: Egó) (c.1795–1860) was a Flemish Romantic painter known for landscapes and architecture in oils and watercolours. Born in Antwerp, he spent much of his career in London (with a few years in Paris and Milan). He is sometimes considered the first Belgian painter. His father, also named Egmont (1671–1743), was a portrait painter who married his mother, Elise Ligard, in 1690.
Egmont’s first recorded sale was of a Claude Lorrain watercolour in 1810. He had some training in Antwerp, where he was successful with painting still lifes and interiors. Although he travelled to Italy, his first command of landscape was the Italianate landscape of Fano, painted in 1817. In England, he began to concentrate on architecture and marine scenes. The high point of his career came in 1820 when he was invited to join the Royal Academy. His paintings were not auctioned by Christie’s during his lifetime, but Christie’s began to sell his paintings after his death. Egmont died in Antwerp in 1860.
Life and work
There are very few paintings by Egmont with dates earlier than 1820 and the London Connection probably had to do with his membership in the Royal Academy. His early works are in a broadly established style, with strong emotional content and a preference for elegant compositions of architectural structures. As Egmont moved away from the earlier approach and focused on the architecture of places, the paintings became more subtle.
Egmont’s work is held in the Royal Collection, the Metropolitan Museum of Art, the National Gallery of Scotland, the J. Paul Getty Museum and the Yale Center for British Art.
He exhibited at the Paris Salon from 1831 to 1839. His paintings were described as “showing us…a mind well versed in the arts, however unpolished”. Egmont claimed to have initially trained under Gijsbreght Leemans in Antwerp, and this influenced his work.
Egmont was an only child of the artist Egmont Haverman (1671-1743). Egmont Haverman was a portrait painter who joined the Antwerp Guild of Saint Luke in 1704 and became a master in 1713. On 16 September
