SOFT LANDING | STAGE 4

The RemoveDERBIS satellites carry out step 1-3 prior to reentering the Earth’s atmosphere. As the final stage of soft landing, step 4 includes the deployment of parachutes as well as a series of on-water preparations.

Bulletproof Vest

Dimensions: 8 x 5 cm

Weight: 2.3 g

LANDING | WATER SURFACE TENSION

The goal is to best preserve the mass and shape of the satellites. As seen previously, bulletproof vests can deform bullets, which indicates that the graphene sheets should not be the first to contact the satellites. From the Mythbusters, we also learn that water can be as hard and as damaging as concrete when hit with a high velocity.

Experiment 2 [Mythbusters] Experiment 3 [Mythbusters] Experiment 1 [Mythbusters]

SHEET PREPARATION | WATER SURFACE TENSION

Therefore, the sheets must be pulled down just before the landing, as the pulling of the sheet will aerate the water with a temporary pocket of air bubbles for the debris to land on with little to no water surface tension.

SHEET PREPARATION | SEA ANCHOR

In the case that the debris does contact the sheet even after slowing down from the water, the sea anchors will prevent the constellation from capsizing.

The photographed Constellation Sentinel can be seen carrying multiple sea anchors as well as its central ballast tank that allows it to pull the net/fabric below the surface of the water.

The first interior shot of the Nemo Space Archive surfaced in 2005 when a photographer took a 3 weeklong boat ride to Point Nemo. The fragment in the photo is said to belong to the Mir Space Station, though no one can really confirm.

IMPACT | RIPPLE EFFECT

Underneath the bulletproof skin, the inhabitable pontoon structures are safe from direct hits but are still subjugated to harsh conditions given the current and ripples that can be generated by nearby captures.

INHABITATION | STRUCTURAL RINGS

In order to keep things in place, a number of circular trusses informed by the Sonic Centre will surround the fragment to provide stability.

RENEWABLE ENERGY | HYDROTHERMAL VENT

A large number of tensioning cables will then hold the truss rings in place, as well as to carry any underwater components of the building.

RENEWABLE ENERGY | HYDROTHERMAL VENT

As studied in the tech report, the facilitation of the satellites will take place above hydrothermal vents. With the help of the offshore thermal energy conversion systems, the building will be able to extract energy from the ocean.

RENEWABLE ENERGY | HYDROTHERMAL VENT

The diagram demonstrates the placement of the OTECs in relation to the vents. The OTECs generate energy through the difference in water temperature between the ocean surface and the thermal vents.

SHEET A-82 | MIR STATION

In correspondence to the section, the plan highlights the key spaces of the Mir Outpost which is set to complete in the year 2024. The key spaces include the main debris facility at the center of the rings, the energy facilities to its left as well as the other smaller fragments around and their designated loading docks.

The reason for its size is simple. An average 500 meteorites reach the surface of the Earth each year, but less than 10 are recovered. This is because most fall into the ocean and statistically, having a 1million km2 surface area will guarantee the capture of at least one meteorite annually, given the total surface area of the Earth.

As seen in the photo, each fragment facility is joined by a designated loading dock. The clarity of the Outpost’s structure is due to the absence of its top layer of graphene, as once every year, the sheets are temporarily removed and cleaned.

The first of its three interior shots capture three of Mir’s fragments lit up by the night sky of the south pacific ocean. Making up a large portion of the photograph is the mythical reinforced graphene membrane that shields the satellites from debris.

The second of its interiors is taken atop one of the columns. With the main focuses being on the fragment in the center. this is the second largest fragment of Mir, which was still presumably under study in year 2024, as inferred by the tents and researchers on site. Directly behind the fragment is the center of the Mir outpost, which contains the main fragment, as seen just below the horizon.

Judging by the photo, the main fragment of Mir looks to be roughly 30m in length and 15 m in width. The facilitation of this fragment is said to be carried out by the stationed crews that conduct hourly check-ins of its temperature, humidity, and other physical condition. Although there have been no public claims of ownership to this fragment, its current estimated 9-digit price tag should make it well worth the effort for the Nemo Space Archive.
