Sounding rockets represent an excellent platform for testing the influence of space conditions during the passage of Earth's atmosphere and re-entry on biological, physical and chemical experiments for astrobiological purposes. We designed a robust functionality biomarker assay to analyze the biological effects of suborbital spaceflights prevailing during ballistic rocket flights. During the TE...

Because of its strong oxidizing properties, high density, low-toxicity and environmentally friendly decomposition products, concentrated hydrogen peroxide has regained popularity as a propellant in many rocket applications. The MEMS-based MIT micro-rocket engine is one such application where 98% liquid hydrogen peroxide and JP7 are proposed as a propellant combination. Like other micro-thruster...

Diplotaxis tenuifolia L. is of important economic value in the fresh-cut industry for its nutraceutical and sensorial properties. However, information on the molecular mechanisms conferring tolerance of harvested leaves to pre- and postharvest stresses during processing and shelf-life have never been investigated. Here, we provide the first transcriptomic resource of rocket by de novo RNA seque...

The number of jet and rocket noise studies has increased in recent years as researchers have sought to better understand aeroacoustic source and radiation characteristics. Although jet and rocket noise is finite-amplitude in nature, little is known about the existence of shock formation and coalescence close to the source. A numerical experiment is performed to propagate finite-amplitude noise ...

This paper presents computational fluid dynamics simulations of the cold gas operation of Pocket Rocket and Mini Pocket Rocket radiofrequency electrothermal microthrusters, replicating experiments performed in both sub-Torr and vacuum environments. This work takes advantage of flow velocity choking to circumvent the invalidity of modeling vacuum regions within a CFD simulation, while still pres...

This paper reports the results of the second phase of a research project to characterize and optimize the design of an advanced launch vehicle for human access to low earth orbit. The vehicle makes use of rocket-based combined-cycle (RBCC) propulsion — a concept combining operating modes of an ejector, ramjet, scramjet, and rocket in a single engine. This research builds on previous work focuse...

Some vegetables have the ability to accumulate cadmium (Cd)at levels that are toxic most other plants. The objective of thisstudy was evaluate Cd accumulation and its effects on edible vegetables. Three species were tested: watercress (Barbarea verna); chicory (Cichorium endivia); rocket (Eruca sativa) four doses (0; 1.5; 3.0; 6.0 mg kg-1), with three replications. We evaluated concentration, f...

Three billion people in the world earn $ 1-2/day. Majority of them live in rural areas with very primitive quality of life. For example in India, which boasts of a very active space and nuclear program, around 60% of rural population have no electricity, use 180 million tons of biomass/year for cooking via primitive wood stoves and have no clean drinking water . Similar is the story in China, B...
