“…Thirteen young people between 15 and 23, recruited from two local support clinics, were interviewed. RESULTS: Lost in space emerged as the core category, capturing aspects of both the experience of self and mental health problems as well as the process of seeking and acquiring help from professional support systems. …”

“…This algorithm is particularly suited to complement nominal lost-in-space algorithms, which may identify stars incorrectly when the focal length and/or optical axis offset deviate from their nominal operational ranges. …”

“…The proposed attitude determination system achieved a 0.001° accuracy, with a 99.1% sky coverage and an ability to reject false-positive while performing a single-frame lost-in-space star identification at a 50 Hz update rate with a total delay of 19 ms, including 13 ms.…”

“…The aim of this study was twofold, firstly to map the published literature on young people’s experiences of seeking help for mental health problems and secondly to validate whether the Lost in Space model was adaptable as a theoretical model of the help-seeking process described in the included articles in this scoping review. …”

“…Understanding of wave environments is critical for the understanding of how particles are accelerated and lost in space. This study shows that in the vicinity of Europa and Ganymede, that respectively have induced and internal magnetic fields, chorus wave power is significantly increased. …”

“…This must have been acquired during global silicate differentiation within the first 30 million years of Solar System formation6 and implies the formation of a complementary (142)Nd-depleted reservoir that either is hidden in the deep Earth6, or was lost to space by impact erosion3,7. Whether this complementary reservoir existed, and whether or not it has been lost from Earth is a matter of debate3,8,9, but has tremendous implications for determining the bulk composition of Earth, its heat content and structure, and for constraining the modes and timescales of its geodynamical evolution3,7,9,10. …”

“…It is often necessary to identify a pattern of observed craters in a single image of the lunar surface and without any prior knowledge of the camera’s location. This so-called “lost-in-space” crater identification problem is common in both crater-based terrain relative navigation (TRN) and in automatic registration of scientific imagery. …”

“…We show that an ancient atmosphere composed of chondritic and cometary volatiles is more enriched in Xe relative to the modern atmosphere, requiring that 8–12 times the present-day inventory of Xe was lost to space. This potentially resolves the long-standing mystery of Earth’s “missing xenon”, with regards to both Xe elemental depletion and isotopic fractionation in the atmosphere. …”
